Title: Starting The Process


1
Starting The Process
  • Chapter 5
  • Database Design For Mere Mortals

2
Conducting Interviews
  • Provide valuable information that can affect the
    design of the database structure
  • Information gathering tool
  • insights from users
  • clarify facts you dont understand
  • Think about questions ahead of time
  • ask open ended questions
  • example how do you feel about our service?

3
Set up guidelines for interviews
  • Set up guidelines for interviews
  • expectations of each person interviewed
  • people more willing to participate and more
    responsive
  • Set a limit of six people or less for each
    interview
  • As much as possible, conduct separate interviews
    for users and management

4
  • Whenever you have to interview several groups of
    people, designate a group leader for each group
  • Prior to the actual interview, let the
    participants know what youre going to discuss
    and how the interview will be conducted.

5
  • Make sure that all participants understand that
    you appreciate their taking part in the interview
    and that their responses to the interview
    questions are valuable to the overall design of
    the project
  • Conduct the interview in a well-lit room,
    separate from distracting noise, with a large
    table and comfortable chairs, have coffee and
    munchies on hand

6
  • If youre not very good at taking notes, either
    assign that task to a dependable transcriber for
    each interview or get the groups permission to
    use a tape recorder to record the interview
  • Give everyone your equal and undivided attention
  • Make sure everyone understands that you are the
    official arbitrator if and when a dispute arises

7
  • Keep the pace of the interview moving
  • Always maintain control of the interview
  • Case Study Mikes Bikes

8
Defining a Mission Statement
  • A good mission statement is succinct and to the
    point
  • Example The purpose of the New Starz Talent
    Agency database is to maintain the data we use
    and to provide the information we need to run the
    day-to-day affairs of our business.

9
  • Not so good mission statement
  • The purpose of the Whatcom County Hearing
    Examiners database is to keep track of
    applications for land use, maintain data on
    applicants, keep a record of all hearings, and
    maintain data for office use.
  • Better mission statement
  • The purpose of the Whatcom County Hearing
    Examiners database is to maintain the data we
    use in support of the services this office
    provides to the citizens of this county

10
  • Possible questions to ask to help define mission
    statement
  • how would you describe the purpose of your
    organization to a new client?
  • What would you say is the purpose of your
    organization
  • What is the major function of your organization?

11
  • How would you describe what your organization
    does?
  • Will you define the single most important reason
    for the existence of your organization?
  • What is the main focus of your organization?

12
Defining the Mission Objectives
  • Statements that represent general tasks
    supported by the data maintained in the database.
  • Declarative sentence that clearly defines a
    general task and is free from unnecessary details

13
Examples
  • we need to maintain complete patient address
    information.
  • we need to keep track of all customer sales.
  • we need to make sure an account representative
    is responsible for no more than twenty accounts
    at any given time.
  • we need to keep track of vehicle maintenance.
  • we need to produce employee phone directories.

14
  • Composing mission objectives
  • determine what types of general tasks that need
    to be supported by the data in the database.
  • Interview questions
  • what kind of work do you perform on a daily
    basis?
  • how would you define your job description?
  • what kind of data do you work with?
  • what types of reports do you generate?
  • what types of things do you keep track of?
  • what types of services does your organization
    provide?
  • how would you describe the type of work you do?
